New technology for N2O destruction helps to reduce greenhouse gas emissions
Petten, The Netherlands and Houston, Texas – April 2008
Energy research Centre of the Netherlands (ECN) and CRI Catalyst Company LP (CRI) have concluded a License
Agreement for a novel catalyst technology developed by ECN to reduce the air emissions of nitrous oxide (N2O). N2O
is identified as a significant greenhouse gas under the Kyoto Protocol having an impact 310 times higher per unit than
CO2. The ECN technology destroys the N2O converting it into harmless nitrogen (N2) and oxygen (O2) and is highly
suitable for reducing N2O emissions from the tail gas streams of industrial and chemical process plants, such as nitric
acid, caprolactam and adipic acid plants, which are significant emitters of N2O. The ECN technology has been tested
under a wide range of conditions and is capable of achieving N2O reductions of more than 90%. It is a robust
technology and in comparison to other technologies on the market it is much more cost effective.
Under the Agreement, ECN will grant to CRI exclusive worldwide rights to applications of its N2O reduction
technology. CRI has completed development of the technology and it is now commercially available worldwide for
implementation on nitric acid and other chemical process plants to meet the greenhouse gas reduction targets under
the Kyoto Agreements.
Jan Willem Erisman, Unit Manager of ECN, noted: “This agreement provides an ideal platform for bringing our
technology to the market on a global scale. CRI is a well-suited partner as a global player with a very good reputation.
This agreement validates the confidence we have in its potential to reduce N2O emissions from the production of nitric
acid and therewith making a significant contribution to reducing global greenhouse gas emissions.”
C. Philipp Brundrett, Business Director of CRI commented: “ECN’s technology is an ideal addition to our portfolio of
environmental catalyst technologies. We believe there is significant market interest in this technology because it can
achieve high levels of N2O emission reduction cost effectively.”
